Acceleration power of fireballs and wind charges gets halved when they are redirected by explosions

steps to reproduce:

1 run command /summon fireball

2 run command /data get entity @n[type=fireball] acceleration_power

3 place tnt near the fireball and ignite it with flint and steel

4 after tnt explodes run the command /data get entity @n[type=fireball] acceleration_power

Expected result: both times the value 0.1 is returned

Observed result: first time the value is 0.1 and the second time it is 0.05

Note that this does not happen in 1.21.8 and the only other way that acceleration power can get reduced is by bouncing the projectile off of a breeze
